Molex 0761652804 Impact 72-Position Backplane Connector Header

Part Overview

The Molex 0761652804 is a 72-position backplane connector header designed for through-hole PCB mounting. This component features male pins arranged in a 9×8 configuration with 0.053" (1.35mm) pitch spacing, utilizing press-fit termination and gold-plated contacts. The connector is classified as obsolete, making identification of compatible alternatives essential for ongoing system support and procurement planning. The active substitute part maintains identical electrical and mechanical specifications while offering improved availability and current product status.

Key Parameters

Substitute Part Grouping Explanation

The Molex 0761653804 qualifies as a direct substitute for the 0761652804 based on strict parameter equivalence across all critical electrical and mechanical specifications. Substitution is valid because both parts share identical values for:

• Connector type, style, and position count (72-position header, male pins, Impact Guide Left)
• Pitch spacing (0.053" / 1.35mm)
• Physical configuration (9 rows × 8 columns)
• Mounting and termination method (through-hole, press-fit)
• Contact material and finish (gold, 30.0µin thickness)
• Electrical ratings (30V, 24 differential pairs)
• Environmental specifications (operating temperature -55°C to 85°C, UL94 V-0)
• Compliance certifications (ROHS3, MSL 1)

The primary distinction is product status: the 0761652804 is obsolete, while the 0761653804 maintains active status with improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761653804 is the appropriate selection for new designs and ongoing procurement. This part maintains full electrical and mechanical compatibility with the obsolete 0761652804 while offering the advantage of active product status and established supply chain availability. Both parts satisfy identical compliance requirements including ROHS3 certification and UL94 V-0 flammability rating. The substitute part is packaged in trays rather than bulk format, which may provide logistical benefits for production environments. No functional or performance differences exist between these components based on provided specifications.

Frequently Asked Questions (FAQ)

Q: Can the 0761653804 be used as a direct replacement for the 0761652804 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including connector type, position count, pitch, mounting method, contact finish, and environmental ratings. Direct substitution is valid without design modification.

Q: What is the primary reason for substitution?

A: The 0761652804 is classified as obsolete. The 0761653804 provides the same functionality with active product status and improved availability.

Q: Are there differences in packaging between these parts?

A: Yes. The 0761652804 is supplied in bulk packaging, while the 0761653804 is supplied in trays. This difference does not affect electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry UL94 V-0 flammability rating, and have MSL 1 (unlimited) moisture sensitivity classification.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in connector type, position count (72), pitch (0.053"), configuration (9×8), mounting method (through-hole), termination (press-fit), contact finish (gold), voltage rating (30V), and operating temperature range (-55°C to 85°C).
