Molex 0761656808 Equivalent & Substitute Parts

Part Overview

The Molex 0761656808 is a 72-position backplane connector header with male pins, designed for through-hole PCB mounting. This connector features an Impact style with guide left orientation and is part of the Impact 76165 series. The part is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance, repairs, and legacy design support. Active equivalent models from the same manufacturer series provide direct functional replacement while maintaining full electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0761656808 are identified based on strict electrical and mechanical parameter matching within the Impact 76165 series. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Manufacturer: Molex
• Series: Impact 76165
• Number of Positions: 72
• Connector Type: Header, Male Pins
• Connector Style: Impact, Guide Left
• Pitch: 0.053" (1.35mm)
• Configuration: 9 Rows × 8 Columns
• Mounting Type: Through Hole
• Termination: Press-Fit
• Contact Layout: 24 Differential Pairs
• Contact Finish: Gold, 30.0µin (0.76µm)
• Color: Black
• Voltage Rating: 30V
• Operating Temperature Range: -55°C ~ 85°C
• Material Flammability: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts (0761653808 and 0761657808) match all critical parameters. The primary distinction is product status: the main part is obsolete, while substitutes are active, and packaging differs (main part packaging unspecified versus tray packaging for substitutes).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (0761653808 and 0761657808) provide direct functional equivalence to the obsolete 0761656808. Selection between substitutes should be based on the following factors:

Product Status: Both substitutes are active products, ensuring ongoing availability and manufacturer support compared to the obsolete main part.

Compliance & Certifications: All three parts maintain identical compliance profiles: ROHS3 compliant, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity level. No compliance trade-offs exist between the main part and substitutes.

Packaging: The main part packaging is unspecified, while both substitutes are supplied in tray packaging. Tray packaging is standard for high-pin-count connectors and facilitates automated assembly processes.

Inventory Availability: Both substitutes maintain comparable stock levels (1005 and 855 units respectively), providing supply continuity for production and repair applications.

Frequently Asked Questions (FAQ)

Q: Can Molex 0761653808 or 0761657808 directly replace the obsolete 0761656808?

A: Yes. Both parts are electrically and mechanically identical to the main part across all specified parameters, including pin count, pitch, contact layout, voltage rating, temperature range, and compliance certifications. Direct substitution is supported without design modification.

Q: What is the difference between the two substitute parts?

A: The substitute parts 0761653808 and 0761657808 are functionally identical. The only documented difference is inventory quantity (1005 units versus 855 units). Both are active products supplied in tray packaging.

Q: Does packaging affect compatibility?

A: No. Tray packaging is a logistics and handling specification that does not affect electrical or mechanical performance. The connector itself remains identical regardless of packaging format.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All three parts share identical compliance specifications: ROHS3 compliant, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity level.

Q: Why is the main part obsolete while substitutes are active?

A: Product status reflects manufacturer lifecycle management. Active substitutes from the same series provide equivalent functionality with ongoing manufacturer support and supply assurance.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: manufacturer (Molex), series (Impact 76165), position count (72), connector type and style (Header Male Pins, Impact Guide Left), pitch (0.053"), configuration (9×8), mounting type (Through Hole), termination (Press-Fit), contact layout (24 Differential Pairs), contact finish (Gold 30.0µin), color (Black), voltage rating (30V), operating temperature (-55°C ~ 85°C), flammability (UL94 V-0), RoHS status (ROHS3), and MSL (1).
