Amphenol ICC 68457-403 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68457-403 is a BERGSTIK® II series rectangular connector header designed for through-hole mounting with 3 positions at 2.54mm pitch. This connector features unshrouded male pins with solder termination and push-pull fastening, suitable for board-to-board applications. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Connector Type: Header — exact match required
Contact Type: Male Pin — exact match required
Mounting Type: Through Hole — exact match required
Termination: Solder — exact match required
Fastening Type: Push-Pull — exact match required
Contact Shape: Square — exact match required
Insulation Height: 0.100" (2.54mm) — exact match required

Engineering Selection Recommendations

All listed substitute parts maintain mechanical and electrical compatibility with the 68457-403 based on identical mating pitch, position count, contact geometry, and flammability certification. Selection should prioritize active product status and compliance requirements:

Primary Recommendation for RoHS Compliance: 54101-T3003LF (Amphenol ICC), 78511-403HLF (Amphenol ICC), 826648-3 (TE Connectivity), 929700-11-03-RK (3M), 929705-01-03-EU (3M), or 929705-01-03-I (3M) — all RoHS compliant with active product status.

For Extended Temperature Range: 54101-T3003LF and 78511-403HLF support -65°C to 125°C operation, exceeding the original part's unspecified range.

For Higher Current Capacity: 78511-403HLF (5A) and 826648-3 (5A) provide increased current handling compared to 3M 929 series alternatives (2.5A).

For Amphenol ICC Series Continuity: 54101-T3003LF (BERGSTIK® series) and 78511-403HLF (BERGSTIK® II series) maintain manufacturer and series alignment with the original part.

For 3M Series Options: 929700-11-03-RK, 929705-01-03-EU, and 929705-01-03-I are all active with RoHS compliance. 929705 variants feature gold plating on both mating and post contacts.

Insulation Color Consideration: 826648-3 features green insulation; all other substitutes maintain black insulation matching the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different insulation height? A: No. The 826648-3 has an insulation height of 0.110" (2.79mm) versus the required 0.100" (2.54mm). This dimensional difference may cause mechanical interference in applications with tight board spacing or connector stacking requirements. All other substitutes maintain the exact 0.100" (2.54mm) specification.

Q: Are all substitute parts pin-compatible with the original 68457-403? A: Yes. All listed substitutes maintain identical mating pitch (0.100" / 2.54mm), contact shape (square), and 3-position, single-row configuration. Physical mating with corresponding receptacles is compatible.

Q: What is the difference between the 929700 and 929705 series from 3M? A: Both are 3M 929 series headers with identical mechanical specifications. The primary difference is contact finish: 929700-01-03 and 929700-11-03-RK use tin or tin-lead finishes, while 929705-01-03-EU and 929705-01-03-I use gold plating on both mating and post contacts. Gold-plated variants provide enhanced corrosion resistance and lower contact resistance.

Q: Why is the 9-146274-0 not listed as a substitute? A: The 9-146274-0 is a 40-position header, not a 3-position header. Position count is a critical substitution parameter and must match exactly. This part is not compatible with applications designed for 3-position connectors.

Q: What is the difference between RoHS compliant and non-compliant parts? A: RoHS compliant parts meet the Restriction of Hazardous Substances directive and contain no lead, mercury, cadmium, or other restricted materials. The original 68457-403 is RoHS non-compliant. For new designs or applications subject to RoHS regulations, select from the compliant alternatives: 54101-T3003LF, 78511-403HLF, 826648-3, 929700-11-03-RK, 929705-01-03-EU, or 929705-01-03-I.

Q: Can I use a substitute with a higher current rating than the original part? A: Yes. Higher current ratings provide additional design margin. The 78511-403HLF (5A) and 826648-3 (5A) support greater current capacity than the 3M 929 series (2.5A). Verify that your application's current requirements do not exceed the substitute part's rating.

Q: What is the difference between tin and gold contact finishes? A: Tin finishes provide standard corrosion resistance and are cost-effective. Gold finishes offer superior corrosion resistance, lower contact resistance, and enhanced reliability in high-reliability applications. The 929705 series (gold-plated) is recommended for applications requiring extended shelf life or exposure to corrosive environments.

Q: Are breakaway connector variants compatible with non-breakaway applications? A: Yes. Breakaway variants (826648-3, 929700-01-03, 929700-11-03-RK, 929705-01-03-EU, 929705-01-03-I) feature the same mating interface as non-breakaway headers. The breakaway feature allows individual pins to be separated; this does not affect compatibility with standard receptacles.
