Substitute Part Grouping Explanation

Substitution eligibility for the 63453-338 is determined by strict adherence to the following core parameters: 38-position configuration, 0.079" (2.00mm) pitch mating, 2-row layout with 0.079" row spacing, through-hole solder termination, push-pull fastening, gold-plated mating contacts, and phosphor bronze contact material. All substitute parts listed maintain these electrical and mechanical specifications. Variations in contact finish thickness, insulation height, contact post length, and post finish are permitted within the substitute group, as these do not affect primary mating functionality or board-level compatibility. Current rating and voltage rating variations are noted where they occur among substitutes, as these represent design differences in the substitute series.

Engineering Selection Recommendations

The 63453-338LF represents the direct equivalent from Amphenol ICC, maintaining identical electrical and mechanical specifications while offering active product status and RoHS compliance. This part is the primary choice for direct replacement in existing designs.

For cross-manufacturer substitution, selection depends on application requirements. The Molex Milli-Grid 79107 series (0791077018, 0791077068, 0791077218, 0791077268) provides active alternatives with compatible mating geometry and push-pull fastening. However, these parts operate at reduced current (1A versus 2A) and voltage (125V versus 200V) ratings compared to the original specification. The 0791077018 variant offers the closest electrical performance match within the Molex series.

The TE Connectivity 1-1977745-8 (AMPMODU series) maintains the 2A current capability and exceeds voltage rating at 250VAC, but operates within a narrower temperature range (-40°C to 105°C versus -55°C to 125°C). This part is suitable for applications not requiring the full original temperature specification.

The Samtec MMS-119-01-H-DV offers the highest current rating (3.9A per contact) and maintains the full -55°C to 125°C temperature range. This part is suitable for applications requiring enhanced current capacity while preserving thermal performance.

All substitute parts maintain RoHS compliance or ROHS3 compliance status, addressing the non-compliance status of the original part. Selection should be based on specific application requirements for current, voltage, and temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the 63453-338LF be used as a direct replacement for the 63453-338?

A: Yes. The 63453-338LF is the direct Amphenol ICC equivalent, maintaining identical pin count (38), pitch (0.079"), row configuration (2 rows), termination method (solder), and fastening type (push-pull). The primary difference is product status (active versus obsolete) and RoHS compliance certification.

Q: What are the key differences between Amphenol and Molex substitutes?

A: The Molex Milli-Grid 79107 series maintains mechanical compatibility but operates at reduced electrical ratings: 1A current versus 2A, and 125V versus 200V. All Molex variants in this group share identical mating pitch, row spacing, and fastening characteristics. Contact post length varies among Molex variants (0.075" to 0.118"), which may affect PCB design considerations.

Q: Are there current or voltage limitations when using Molex substitutes?

A: Yes. Molex Milli-Grid 79107 variants (0791077018, 0791077068, 0791077218, 0791077268) are rated for 1A at 125V, compared to the original 2A at 200V specification. Applications requiring the full original electrical performance should not use these substitutes without circuit redesign.

Q: How do contact post length variations affect PCB compatibility?

A: Contact post length determines solder joint depth and PCB hole engagement. The original 63453-338 specifies 0.098" (2.50mm) post length. Molex variants range from 0.075" to 0.118", TE Connectivity offers 0.102", and Samtec provides 0.115". Shorter posts may reduce solder joint strength; longer posts may interfere with component placement. PCB design review is necessary when post length differs from the original specification.

Q: Which substitute offers the best performance upgrade?

A: The Samtec MMS-119-01-H-DV provides the highest current rating (3.9A per contact) while maintaining the full -55°C to 125°C temperature range. This part is suitable for applications requiring enhanced current capacity. The TE Connectivity 1-1977745-8 offers 250VAC voltage rating, exceeding the original 200V specification.

Q: Are all substitutes RoHS compliant?

A: The original 63453-338 is RoHS non-compliant. All listed substitutes are either RoHS Compliant or ROHS3 Compliant, addressing regulatory requirements for new designs and production.

Q: What packaging options are available?

A: The 63453-338LF is supplied in Tube packaging. Molex variants and Samtec MMS-119-01-H-DV are also supplied in Tube packaging. TE Connectivity 1-1977745-8 packaging is not specified in available data.
