Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 7-146250-5

The 7-146250-5 is the manufacturer-recommended successor to the obsolete 1-104433-8. Both components share identical AMPMODU Mod II series classification and maintain full compatibility across all critical parameters: 50 positions, 2-row configuration, 0.100" pitch, through-hole mounting, and push-pull fastening. The 7-146250-5 is active in production status, ensuring long-term availability. Operating temperature range (-65°C to 105°C) and current rating (3A) are identical. The primary difference is the contact finish on the mating surface, which transitions from gold to tin. This change does not affect electrical compatibility for standard applications.

Secondary Recommendations for Active Alternatives:

Amphenol ICC (FCI) BERGSTIK® II Series (78548-150, 78548-150H, 78548-650, 68779-150HLF): These connectors maintain full mechanical and electrical compatibility with the original part. All feature 50 positions, 2 rows, 0.100" pitch, through-hole mounting, and push-pull fastening. The BERGSTIK® II series offers enhanced contact durability through phosphor bronze construction and gold or gold GXT™ mating finishes. Operating temperature range extends to 130°C for model 68779-150HLF. These parts are active in production.

Preci-Dip 892-18-050-10-001101: This connector maintains core compatibility with 50 positions, 2 rows, 0.100" pitch, and through-hole mounting. The 892 series operates across -55°C to 125°C and supports 3A current rating. RoHS3 compliance is achieved. Contact length specifications differ slightly (0.236" mating vs. 0.318" on original), which may require PCB layout verification.

Hirose Electric A1-50PA-2.54DSA(71): This connector provides full mechanical compatibility with 50 positions, 2 rows, 0.100" pitch, and through-hole mounting. RoHS3 compliance is achieved. Operating temperature range is -55°C to 85°C, which is narrower than the original specification. This part is suitable for applications not requiring the full -65°C lower temperature limit.

Samtec Inc. BBD-125-T-B: This connector differs in contact geometry (circular vs. square) and insulation height (0.335" vs. 0.090"), making it suitable only for applications where these dimensional changes are acceptable. RoHS3 compliance is achieved. This part should be selected only when mechanical constraints permit the larger insulation height.

Compliance Considerations:

For applications requiring RoHS compliance, the following active alternatives are available:

Amphenol ICC 68779-150HLF (RoHS Compliant)
Preci-Dip 892-18-050-10-001101 (ROHS3 Compliant)
Hirose Electric A1-50PA-2.54DSA(71) (ROHS3 Compliant)
Samtec Inc. BBD-125-T-B (ROHS3 Compliant)

For applications where RoHS non-compliance is acceptable, all listed alternatives remain viable.

Frequently Asked Questions (FAQ)

Q: Can the 7-146250-5 directly replace the 1-104433-8 without PCB modifications?

A: Yes. The 7-146250-5 maintains identical pitch (0.100"), position count (50), row configuration (2), mounting type (through-hole), and fastening mechanism (push-pull) as the 1-104433-8. Insulation height is identical at 0.090" (2.29mm). No PCB layout changes are required. The contact finish change from gold to tin does not affect mechanical fit or electrical performance in standard applications.

Q: What is the significance of the contact finish difference between the original part and substitute options?

A: The original 1-104433-8 features gold mating contacts (15.0µin thickness) with tin-lead post finish. Substitute parts vary in mating finish: 7-146250-5 uses tin, BERGSTIK® II series use gold or gold GXT™, and other alternatives use gold or tin. Gold finishes provide superior corrosion resistance and are preferred for low-signal applications. Tin finishes are acceptable for standard digital and power applications. Selection depends on application requirements and environmental exposure.

Q: Are there dimensional constraints when substituting the 1-104433-8?

A: Most substitute parts maintain the same overall contact length (0.533" to 0.538") and insulation height (0.090" to 0.100"), ensuring compatibility with existing PCB footprints. Exceptions include the Preci-Dip 892-18-050-10-001101 (0.458" overall contact length) and Samtec BBD-125-T-B (0.335" insulation height). These parts require verification against PCB design specifications before selection.

Q: Which substitute part offers the widest operating temperature range?

A: The Amphenol ICC 68779-150HLF (BERGSTIK® II series) operates from -65°C to 130°C, exceeding the original specification of -65°C to 105°C. This part is suitable for applications requiring extended high-temperature performance.

Q: What packaging options are available for substitute parts?

A: Packaging varies by manufacturer and part number. Options include bulk packaging (Amphenol ICC, Preci-Dip), tube packaging (Samtec), tray packaging (Hirose), and bag packaging (Amphenol ICC 68779-150HLF). Packaging selection does not affect electrical or mechanical compatibility; it is determined by procurement and assembly requirements.

Q: Are all substitute parts RoHS compliant?

A: No. The original 1-104433-8 is RoHS non-compliant. Among substitutes, RoHS compliance status varies: Amphenol ICC 68779-150HLF is RoHS Compliant; Preci-Dip 892-18-050-10-001101, Hirose A1-50PA-2.54DSA(71), and Samtec BBD-125-T-B are ROHS3 Compliant. Other alternatives (7-146250-5, 2350-6221-TG, 54102-T30-25, 78548-150, 78548-150H, 78548-650) are RoHS non-compliant. Selection depends on regulatory requirements for the end application.

Q: What is the difference between the BERGSTIK® and BERGSTIK® II series?

A: Both series maintain identical core specifications for 50-position, 2-row, 0.100" pitch connectors. BERGSTIK® II (models 68779-150HLF, 78548-150, 78548-150H, 78548-650) represents the current active product line with enhanced contact materials (phosphor bronze) and extended temperature ratings. BERGSTIK® (model 54102-T30-25) is an earlier generation. Both are mechanically and electrically compatible with the original 1-104433-8.

Q: Can the BBD-125-T-B be used as a direct substitute despite its circular contact shape?

A: The BBD-125-T-B maintains 50 positions, 2 rows, 0.100" pitch, through-hole mounting, and push-pull fastening. However, its circular contact geometry (versus square on the original) and significantly larger insulation height (0.335" versus 0.090") require verification against PCB footprint and mating connector specifications. This part is suitable only when mechanical constraints permit these dimensional differences.

Q: Which substitute offers the best long-term availability?

A: The TE Connectivity 7-146250-5 is the manufacturer-recommended replacement and is active in production. Amphenol ICC BERGSTIK® II series (68779-150HLF, 78548-150, 78548-150H, 78548-650) are also active and widely available. Both manufacturers maintain established supply chains for these product lines.
