Parameter Comparison

Engineering Selection Recommendations

The Molex 0761453608 is the direct equivalent for the obsolete 0761452608. Both parts are manufactured by Molex within the Impact 76145 series and maintain identical electrical and mechanical specifications. The 0761453608 carries active product status, ensuring continued availability and supply chain reliability.

Both parts comply with ROHS3 requirements and carry UL94 V-0 flammability certification, meeting regulatory and safety standards for backplane connector applications. The moisture sensitivity level of 1 (Unlimited) indicates no special handling requirements during storage or assembly.

The primary distinction is packaging format: the 0761452608 is supplied in bulk, while the 0761453608 is supplied in trays. This packaging difference does not affect electrical or mechanical performance and is determined by procurement and inventory management requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0761453608 directly replace the 0761452608 in existing designs?

A: Yes. The 0761453608 is a direct equivalent with identical electrical and mechanical parameters, including position count, pitch, connector style, mounting type, and contact specifications. No design modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The 0761452608 is obsolete and supplied in bulk packaging, while the 0761453608 is active and supplied in tray packaging. All functional specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical certifications: ROHS3 compliance, UL94 V-0 flammability rating, and moisture sensitivity level 1 (Unlimited). Both operate across the same temperature range (-55°C ~ 85°C) and voltage rating (30V).

Q: Does packaging format affect connector performance?

A: No. Packaging format (bulk versus tray) is a logistics consideration only and does not impact electrical or mechanical performance, contact integrity, or reliability.

Q: Why should I transition from the 0761452608 to the 0761453608?

A: The 0761452608 is classified as obsolete, which may result in supply constraints and increased lead times. The 0761453608 maintains active product status, ensuring reliable availability and consistent supply chain support for current and future production requirements.
