Engineering Selection Recommendations

All four substitute parts maintain active product status and comply with RoHS requirements, ensuring long-term availability and regulatory alignment. The Amphenol ICC BERGSTIK® series (77313-101-50LF and 77313-118-50LF) provides extended operating temperature range (-65°C to 130°C) compared to Sullins alternatives (-65°C to 125°C), making them suitable for applications requiring higher thermal performance. The Sullins PBC25DAAN and PEC25DAAN parts offer higher inventory levels (1881 and 1730 units respectively) for applications prioritizing supply chain continuity.

Contact length variations between the main part and substitutes reflect different PCB stack-up requirements. The Molex 0702800653 features longer post length (0.175") suitable for thicker PCB assemblies, while substitute parts with shorter post lengths (0.095" to 0.120") accommodate standard PCB thicknesses. Mechanical envelope constraints must be evaluated against specific application requirements.

Contact finish selection differs between parts. The Molex and Amphenol ICC parts feature gold mating surfaces, while the Sullins PEC25DAAN uses tin finish. The Sullins PBC25DAAN retains gold finish. Contact finish selection impacts corrosion resistance and long-term reliability in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 77313-101-50LF directly replace the Molex 0702800653?

A: Yes. Both parts share identical connector type, contact configuration, pitch, row spacing, mounting method, and termination. The 77313-101-50LF is electrically and mechanically compatible. Differences in contact length and insulation height require verification against PCB design specifications to ensure proper mating depth and clearance.

Q: What is the primary difference between Amphenol ICC 77313-101-50LF and 77313-118-50LF?

A: The primary difference is contact post length. The 77313-101-50LF has 0.095" post length, while the 77313-118-50LF has 0.120" post length. Both maintain identical mating contact length (0.230") and overall electrical performance. Selection depends on PCB thickness and solder joint requirements.

Q: Are Sullins PBC25DAAN and PEC25DAAN interchangeable?

A: Both parts are mechanically and electrically equivalent with identical pitch, position count, and mounting configuration. The primary difference is contact finish: PBC25DAAN features gold mating surface, while PEC25DAAN features tin mating surface. Selection depends on application corrosion resistance requirements and compatibility with mating connector finish.

Q: Do all substitute parts meet the same RoHS compliance level?

A: All parts are RoHS compliant. The Molex 0702800653, Sullins PBC25DAAN, and Sullins PEC25DAAN are ROHS3 compliant. The Amphenol ICC parts (77313-101-50LF and 77313-118-50LF) are RoHS compliant. Both compliance levels satisfy regulatory requirements for electronic component use.

Q: What is the impact of different insulation materials on part selection?

A: The Molex 0702800653 uses Liquid Crystal Polymer (LCP) glass-filled insulation, while Amphenol ICC parts use Thermoplastic, and Sullins parts use Polybutylene Terephthalate (PBT). All materials meet UL94 V-0 flammability requirements. Material selection affects mechanical properties and thermal performance but does not impact electrical compatibility for standard applications.

Q: Which substitute part offers the best inventory availability?

A: The Sullins PBC25DAAN provides the highest inventory level at 1881 units, followed by PEC25DAAN at 1730 units. Both exceed the Molex original part inventory (1045 units) and Amphenol ICC alternatives (1248 and 1292 units respectively).

Q: Are operating temperature ranges critical for substitution?

A: Operating temperature range differences exist between parts. Amphenol ICC parts support -65°C to 130°C, while Sullins parts support -65°C to 125°C. The Molex original part does not specify operating temperature. Applications requiring operation above 125°C must use Amphenol ICC alternatives. Standard applications within -65°C to 125°C range are compatible with all substitute parts.
