Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146250-3

The 5-146250-3 is the direct active equivalent from the original manufacturer. This part maintains identical pitch spacing, position count, row configuration, contact dimensions, and operating temperature range as the obsolete 4-146262-1. The primary difference is the contact finish specification (tin versus tin-lead on mating surfaces), which does not affect functional compatibility. The 5-146250-3 carries RoHS Compliant status and is actively produced with substantial inventory availability (50,020 units), making it the optimal choice for design continuity and supply chain stability.

Secondary Recommendations: Molex C-Grid Series

The Molex 0702871148 (C-Grid 70287 series) provides the closest dimensional match to the original part, including kinked pin termination identical to the 4-146262-1. This part maintains the same contact post length (0.125" / 3.18mm) and overall contact length (0.535" / 13.59mm). The gold mating finish and glass-filled LCP insulation material offer enhanced durability. ROHS3 compliance and active production status support long-term availability.

The Molex 0010897063 and 0702871148 are suitable for applications requiring gold-plated contacts for improved corrosion resistance, though contact length variations require PCB layout verification.

Alternative Options: 3M and Würth Elektronik

The 3M 2306-6221-TP maintains identical contact dimensions and current rating but carries RoHS non-compliant status, limiting applicability to legacy systems. The Würth Elektronik 61300621121 (WR-PHD series) offers ROHS3 compliance and extended operating temperature range (-40°C to 105°C) with gold-plated contacts, though reduced mating contact length (0.236" / 6.00mm) requires design verification.

Amphenol ICC BERGSTIK® II Option

The 68481-106HLF provides the widest operating temperature range (-65°C to 130°C) and RoHS compliance. Phosphor bronze contact material and gold finish enhance signal integrity and corrosion resistance. Reduced contact post length (0.095" / 2.41mm) necessitates PCB footprint evaluation.

Compliance Considerations

All recommended substitutes maintain UL94 V-0 flammability rating and 3A current capacity. For new designs, ROHS3-compliant options (Molex C-Grid series, Würth Elektronik, Amphenol ICC) are preferred. The TE Connectivity 5-146250-3 remains the optimal choice for direct replacement in existing designs due to dimensional and electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 5-146250-3 directly replace the obsolete 4-146262-1 without PCB modifications?

A: Yes. The 5-146250-3 maintains identical pitch spacing (0.100" / 2.54mm), position count (6 in 2 rows), contact dimensions, and mounting type. The only specification change is the mating contact finish (tin instead of tin-lead), which does not affect mechanical or electrical compatibility. No PCB layout changes are required.

Q: What is the primary difference between the TE Connectivity 5-146250-3 and Molex 0702871148?

A: Both parts are functionally compatible with the original 4-146262-1. The 5-146250-3 uses standard solder termination, while the 0702871148 features kinked pin termination identical to the original part. The 0702871148 includes gold-plated mating contacts and glass-filled LCP insulation, offering enhanced durability. Contact post length is identical (0.125" / 3.18mm) in both parts.

Q: Are all substitute parts RoHS compliant?

A: No. The 3M 2306-6221-TP is RoHS non-compliant and should be used only in legacy applications. All other recommended substitutes (TE Connectivity 5-146250-3, Molex C-Grid series, Würth Elektronik 61300621121, and Amphenol ICC 68481-106HLF) carry RoHS or ROHS3 compliance certification.

Q: What is the significance of contact finish differences (tin versus gold)?

A: Tin-plated contacts (5-146250-3) provide standard electrical performance and cost efficiency. Gold-plated contacts (Molex, Würth Elektronik, Amphenol ICC options) offer superior corrosion resistance and are preferred for high-reliability applications, automotive systems, and environments with moisture or chemical exposure. Both finishes maintain equivalent electrical conductivity for 3A current applications.

Q: Do all substitute parts have identical operating temperature ranges?

A: No. The original 4-146262-1 and TE Connectivity 5-146250-3 operate from -65°C to 105°C. The 3M 2306-6221-TP operates from -55°C to 105°C (narrower low-temperature range). The Würth Elektronik 61300621121 operates from -40°C to 105°C. The Amphenol ICC 68481-106HLF extends to -65°C to 130°C (widest range). Verify application temperature requirements before selection.

Q: What packaging options are available for these substitute parts?

A: The TE Connectivity 5-146250-3 is supplied in bulk packaging. Molex C-Grid series parts are available in bulk or tray packaging depending on part number. The 3M 2306-6221-TP packaging is not specified. Würth Elektronik 61300621121 is supplied in bulk. Amphenol ICC 68481-106HLF is supplied in bag packaging. Confirm packaging requirements with procurement specifications.

Q: Are there dimensional variations that require PCB layout changes?

A: Minor variations exist in overall contact length and insulation height across substitute options. The TE Connectivity 5-146250-3 and Molex 0702871148 maintain dimensions within 0.002" of the original part. The Molex 0901310763 series and Würth Elektronik 61300621121 show greater variation (0.054" to 0.079" shorter overall contact length), requiring PCB footprint verification. Amphenol ICC 68481-106HLF is 0.053" shorter. Consult mechanical drawings before design implementation.

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

A: The TE Connectivity 5-146250-3 is the recommended choice, with 50,020 units in active inventory and ongoing production as part of the AMPMODU Mod II series. Molex C-Grid series parts (0702871148 with 876 units, 0901310763 with 10,326 units) provide secondary supply options. All recommended substitutes are classified as active products with established manufacturing continuity.
