Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters: 38-position count, 0.079" (2.00mm) pitch, 2-row configuration with 0.079" row spacing, through-hole solder termination, push-pull fastening, gold mating contact finish, and phosphor bronze contact material. Substitute parts must maintain compatibility with the original PCB footprint and electrical performance envelope.

The substitute parts are grouped into two categories:

Direct Amphenol ICC Variant: 63453-038LF maintains identical electrical and mechanical specifications with updated RoHS compliance and active product status.

Cross-Manufacturer Alternatives: Molex Milli-Grid 79107 series (0791077018, 0791077068, 0791077218, 0791077268), TE Connectivity AMPMODU (1-1977745-8), and Samtec MMS series (MMS-119-01-H-DV) provide functional equivalence with variations in contact finish thickness, post length, and current rating specifications.

Engineering Selection Recommendations

Primary Recommendation: 63453-038LF

The Amphenol ICC 63453-038LF is the direct variant of the obsolete 63453-038, maintaining identical electrical and mechanical specifications while achieving active product status and RoHS compliance. This part provides the most direct replacement path with no design modifications required.

Secondary Recommendations for Cross-Manufacturer Substitution:

Molex Milli-Grid 79107 series parts (0791077018, 0791077068, 0791077218, 0791077268) provide functional equivalence with active status and ROHS3 compliance. These parts maintain the required 38-position, 2.00mm pitch configuration and push-pull fastening. However, they operate at reduced current rating (1A versus 2A) and voltage rating (125V versus 200V), requiring circuit-level verification for applications demanding the original 2A/200V specifications.

TE Connectivity 1-1977745-8 (AMPMODU series) offers RoHS compliance and active status with a narrower operating temperature range (-40°C to 105°C versus -55°C to 125°C). Voltage rating is 250VAC, exceeding the original specification.

Samtec MMS-119-01-H-DV provides the highest current capacity (3.9A per contact) with ROHS3 compliance and active status. This part features gold-plated posts and liquid crystal polymer insulation, differing from the original tin-plated posts and PCT insulation.

Frequently Asked Questions (FAQ)

Q: Can 63453-038LF be used as a direct drop-in replacement for 63453-038?

A: Yes. The 63453-038LF maintains identical electrical and mechanical specifications including pitch, position count, row configuration, contact materials, and operating temperature range. No PCB redesign is required.

Q: What are the key differences between Amphenol ICC 63453-038LF and Molex 0791077018?

A: Both maintain the 38-position, 2.00mm pitch, 2-row configuration and push-pull fastening. Primary differences include current rating (2A versus 1A), voltage rating (200V versus 125V), contact post length (2.50mm versus 3.00mm), and insulation material (PCT versus thermoplastic). Circuit verification is required if the application demands 2A or 200V operation.

Q: Are there packaging differences among the substitute parts?

A: Yes. The 63453-038LF is supplied in tube packaging. Molex parts 0791077018 is supplied in tube; 0791077068, 0791077218, and 0791077268 have unspecified packaging. Samtec MMS-119-01-H-DV is supplied in tube. Verify packaging requirements with your procurement process.

Q: Which substitute part has the best compliance profile?

A: All active substitute parts achieve RoHS compliance (either RoHS or ROHS3). The 63453-038LF, Molex series, TE Connectivity, and Samtec parts all meet current regulatory requirements. The original 63453-038 is RoHS non-compliant.

Q: Can Samtec MMS-119-01-H-DV be used in high-current applications?

A: The MMS-119-01-H-DV is rated for 3.9A per contact, exceeding the original 2A specification. However, it features gold-plated posts and different insulation material (LCP versus PCT), requiring design validation for thermal and mechanical compatibility.

Q: What is the impact of contact post length variation?

A: Contact post length affects PCB hole depth and solder joint formation. The original 63453-038 specifies 0.098" (2.50mm) posts. Molex variants range from 0.075" to 0.118", TE Connectivity specifies 0.102", and Samtec specifies 0.115". PCB design must accommodate the selected post length to ensure proper solder joint quality and mechanical retention.

Q: Are there temperature range limitations with cross-manufacturer substitutes?

A: The original 63453-038 operates -55°C to 125°C. All Amphenol ICC and Samtec alternatives maintain this range. Molex parts maintain this range. TE Connectivity 1-1977745-8 operates -40°C to 105°C, which is narrower. Applications requiring full -55°C to 125°C operation should avoid the TE Connectivity part.
