Molex 0761558107 Equivalent & Substitute Parts

Part Overview

The Molex 0761558107 is a 120-position backplane connector header with male pins, designed for through-hole PCB mounting. This connector features an Impact style with guide right configuration, 12 rows by 10 columns arrangement, and 0.053" (1.35mm) pitch spacing. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Active alternatives within the same series provide identical electrical and mechanical specifications while maintaining current product status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0761558107 are determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Header, Male Pins with Impact, Guide Right configuration
• Position Count & Layout: 120 positions arranged in 12 rows × 10 columns
• Pitch Specification: 0.053" (1.35mm) center-to-center spacing
• Electrical Ratings: 30V voltage rating and contact layout of 40 differential pairs
• Physical Characteristics: Through-hole press-fit termination with gold contact finish
• Environmental Compliance: UL94 V-0 flammability, ROHS3 compliance, and -55°C ~ 85°C operating range

The substitute parts 0761555107 and 0761559107 maintain identical specifications across all these parameters while differing only in product status (active vs. obsolete) and packaging configuration (tray packaging).

Parameter Comparison

Engineering Selection Recommendations

Both 0761555107 and 0761559107 are direct functional equivalents to the obsolete 0761558107. Selection between these active alternatives should be based on the following criteria:

Product Status: The main part (0761558107) is obsolete. Both substitute parts maintain active product status, ensuring long-term availability and continued manufacturer support.

Compliance & Certifications: All three parts are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for flammability. No compliance differentiation exists between the main part and substitutes.

Packaging Consideration: The main part is supplied in bulk packaging, while both substitutes are supplied in tray packaging. Tray packaging provides improved handling and storage characteristics for production environments.

Inventory & Procurement: Both substitute parts maintain higher inventory levels (885 Pcs and 733 Pcs respectively) compared to the obsolete main part (813 Pcs), supporting consistent procurement availability.

For new designs or ongoing production requiring this connector type, either 0761555107 or 0761559107 is suitable. Selection may be determined by packaging preference, supplier availability, or existing procurement agreements.

Frequently Asked Questions (FAQ)

Q: Can 0761555107 and 0761559107 be used interchangeably with 0761558107?

A: Yes. All three parts are electrically and mechanically identical across all specified parameters, including connector type, position count, pitch, contact finish, and electrical ratings. The substitutes differ only in product status (active vs. obsolete) and packaging format (tray vs. bulk).

Q: Why are there multiple part numbers for the same connector specification?

A: Multiple part numbers within the Impact 76155 series reflect different manufacturing batches, packaging configurations, or distribution channels. All variants maintain identical electrical and mechanical specifications, allowing functional interchangeability.

Q: Does the tray packaging of substitute parts affect PCB assembly compatibility?

A: No. Tray packaging is a logistics and handling consideration only. The connector itself maintains identical through-hole press-fit termination and PCB footprint. Assembly processes remain unchanged.

Q: Are there any temperature or voltage derating considerations when substituting these parts?

A: No. All three parts share identical operating temperature range (-55°C ~ 85°C) and voltage rating (30V). No derating or environmental adjustments are required when substituting between these part numbers.

Q: What is the significance of the 40 differential pairs contact layout?

A: The 40 differential pairs specification indicates the connector's internal signal routing configuration. This parameter is identical across all three parts, ensuring equivalent signal integrity and impedance characteristics for high-speed differential signaling applications.

Q: Should I prioritize 0761555107 or 0761559107 for new procurement?

A: Both parts are functionally equivalent. Selection should be based on supplier availability, inventory levels, packaging preference, or existing procurement agreements. No technical differentiation exists between them.
