M80-7913442 Equivalent & Substitute Parts

Part Overview

The M80-7913442 is a rectangular connector header manufactured by Harwin Inc., part of the Datamate L-Tek series. This is a through-hole, right-angle header with 34 positions at 2.00mm pitch, designed for board-to-board or cable connections. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M80-7913442 is determined by strict alignment of the following critical parameters:

• Connector geometry: 34 positions, 2 rows, 0.079" (2.00mm) mating pitch and row spacing
• Mounting configuration: Through-hole, right-angle orientation
• Electrical characteristics: Contact material (phosphor bronze), contact finish (gold mating surface, tin post), and shrouding type (shrouded 4-wall)
• Termination method: Solder termination with latch holder fastening
• Compliance standards: ROHS3 compliance and UL94 V-0 flammability rating

The substitute part 0878337000 (Molex Milli-Grid 87833 series) meets these core substitution criteria. Variations in contact length, insulation height, contact finish thickness, and operating temperature range do not preclude substitution when the primary functional and electrical parameters align.

Engineering Selection Recommendations

The Molex 0878337000 is a direct substitute for the obsolete Harwin M80-7913442 based on the following engineering criteria:

Product Status: The M80-7913442 is obsolete, while the 0878337000 is active and currently in production. This ensures long-term availability and supply chain continuity for new designs and ongoing maintenance requirements.

Compliance Alignment: Both components are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and classified under the same HTSUS code (8536.69.4040). This ensures regulatory equivalence across all applicable standards.

Functional Compatibility: Both connectors share identical core specifications: 34-position, 2-row configuration with 2.00mm mating pitch and row spacing, through-hole right-angle mounting, shrouded 4-wall design, solder termination, and latch holder fastening. Contact material, finish type, and electrical properties are equivalent.

Operating Conditions: The M80-7913442 operates from -55°C to 125°C, while the 0878337000 operates from -55°C to 105°C. For applications within the 0878337000 temperature range, full substitution is appropriate. Applications requiring operation above 105°C require engineering evaluation.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0878337000 directly replace the Harwin M80-7913442 in existing designs?

A: Yes, for applications operating within -55°C to 105°C. Both connectors share identical mating pitch, row spacing, position count, mounting type, shrouding, and termination method. The primary design consideration is the operating temperature range difference.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) Operating temperature range: M80-7913442 supports -55°C to 125°C, while 0878337000 supports -55°C to 105°C; (2) Contact shape: M80-7913442 has circular contacts, 0878337000 has square contacts; (3) Insulation material: M80-7913442 uses PA46 nylon, 0878337000 uses glass-filled nylon; (4) Contact finish thickness varies slightly between models; (5) Number of positions loaded: M80-7913442 has all 34 positions loaded, 0878337000 has 33 positions loaded.

Q: Are there any packaging differences?

A: The M80-7913442 packaging information is not specified in the available data. The 0878337000 is supplied in tube packaging.

Q: Do both connectors meet the same regulatory standards?

A: Yes. Both are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and share the same HTSUS classification (8536.69.4040). Regulatory equivalence is confirmed.

Q: What is the current rating difference, and does it affect substitution?

A: The M80-7913442 has a specified current rating of 2.6A. The 0878337000 current rating is not provided in the available data. For applications requiring the full 2.6A rating, engineering evaluation of the Molex part is necessary.

Q: Can the 0878337000 be used in high-temperature applications above 105°C?

A: No. The 0878337000 is rated to 105°C maximum. Applications requiring operation above 105°C must use the M80-7913442 or identify an alternative component rated for the required temperature range.
