Molex 0760558103 Equivalent & Substitute Parts

Part Overview

The Molex 0760558103 is a 150-position backplane connector header with male pins, designed for through-hole PCB mounting. This connector features an Impact style with guide right configuration, 15 rows by 10 columns arrangement, and 0.053" (1.35mm) pitch spacing. The part is classified as obsolete, making identification of active equivalent alternatives necessary for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0760558103 is determined by strict equivalence across all electrical and mechanical parameters within the Impact 76055 series. The following criteria establish valid substitutes:

• Identical number of positions: 150
• Identical pitch spacing: 0.053" (1.35mm)
• Identical row and column configuration: 15 × 10
• Identical connector type: Header, Male Pins
• Identical connector style: Impact, Guide Right
• Identical mounting type: Through Hole
• Identical termination method: Press-Fit
• Identical contact finish: Gold, 30.0µin (0.76µm)
• Identical color: Black
• Identical voltage rating: 30V
• Identical operating temperature range: -55°C ~ 85°C
• Identical material flammability rating: UL94 V-0
• Identical RoHS compliance: ROHS3 Compliant
• Identical moisture sensitivity level: 1 (Unlimited)

The primary distinction between the main part and substitutes is product status and packaging configuration. The main part (0760558103) is obsolete with no specified packaging, while substitute parts are active with defined packaging (Tray).

Parameter Comparison

Engineering Selection Recommendations

Both Molex 0760555103 and Molex 0760559103 are direct functional equivalents to the obsolete 0760558103. Selection between active alternatives is based on the following factors:

Product Status: The main part 0760558103 is obsolete. Both substitute parts (0760555103 and 0760559103) are active products, ensuring long-term availability and continued manufacturing support.

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

Packaging Configuration: Both substitutes are supplied in Tray packaging, which is standard for production environments. The main part's packaging specification is not defined, but tray packaging is the industry standard for this connector category.

Inventory Availability: The 0760559103 offers the highest current stock level at 1021 pieces, followed by 0760555103 at 700 pieces. The obsolete 0760558103 maintains 849 pieces in inventory but is no longer manufactured.

For new designs or ongoing procurement, either 0760555103 or 0760559103 is suitable. For maximum supply chain continuity, 0760559103 is preferred due to higher inventory levels.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0760555103 or 0760559103 be used as direct replacements for the 0760558103?

A: Yes. Both parts are electrically and mechanically identical to the main part across all specified parameters, including connector configuration, pitch, voltage rating, temperature range, and compliance certifications. The only differences are product status (active vs. obsolete) and packaging specification (Tray).

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

A: The Molex 0760555103 and 0760559103 are functionally identical. Both are Impact 76055 series 150-position headers with identical electrical and mechanical specifications. The primary distinction is inventory availability, with 0760559103 currently stocked at higher quantities.

Q: Why is the main part listed as obsolete?

A: The 0760558103 has been superseded by active alternatives within the same Impact 76055 series. Molex continues to manufacture equivalent parts under different part numbers to maintain product line continuity and manufacturing efficiency.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. All three parts share identical connector type, style, pitch, row/column configuration, mounting method, and termination type. PCB layouts and mating connector specifications remain unchanged.

Q: What packaging is supplied with the substitute parts?

A: Both substitute parts (0760555103 and 0760559103) are supplied in Tray packaging, which is standard for high-pin-count connectors in production environments.

Q: Do all three parts meet the same regulatory and compliance standards?

A: Yes. All three parts are ROHS3 Compliant, carry UL94 V-0 material flammability rating, and have MSL 1 (Unlimited) moisture sensitivity level. No compliance differences exist between the main part and substitutes.
