Molex 0877591075 Equivalent & Substitute Parts

Part Overview

The Molex 0877591075 is a surface mount rectangular connector header in the Milli-Grid 87759 series, configured for 10 positions at 2.00mm pitch with 2 rows. This board-to-board connector features male pins with gold-plated mating contacts and tin-plated posts, designed for push-pull fastening applications. The part is active in production status with full position loading and UL94 V-0 flammability rating. Equivalent parts are necessary when addressing supply constraints, packaging requirements, or specific application needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0877591075 is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm) — exact match required
• Number of Positions: 10 — exact match required
• Number of Rows: 2 — exact match required
• Row Spacing - Mating: 0.079" (2.00mm) — exact match required
• Contact Type: Male Pin — exact match required
• Mounting Type: Surface Mount — exact match required
• Termination: Solder — exact match required
• Fastening Type: Push-Pull — exact match required
• Style: Board to Board or Cable — compatible with Board to Board
• Shrouding: Unshrouded — exact match required
• Material Flammability Rating: UL94 V-0 — exact match required

The three Amphenol ICC (FCI) Minitek® 2.00mm series parts listed below meet all critical substitution criteria. Variations in contact length, number of positions loaded, packaging format, and contact material composition do not preclude substitution when the above parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three Amphenol ICC (FCI) substitute parts maintain active production status and comply with RoHS and UL94 V-0 flammability requirements, ensuring regulatory alignment with the Molex 0877591075. The Amphenol parts provide specified current and voltage ratings (2A AC/DC, 200V AC/DC) not documented for the original part.

57202-G52-05LF is supplied in bulk packaging and features the longest mating contact length at 0.157" (4.00mm), suitable for applications requiring maximum contact engagement depth.

57202-G53-05A09LF is supplied in tape and reel format with 9 positions loaded and includes pick-and-place features, optimized for high-volume automated assembly environments. This configuration is appropriate when the application design accommodates 9-position loading.

57202-G53-05ALF is supplied in tape and reel format with all 10 positions loaded and includes pick-and-place features, providing direct functional equivalence to the original part in standard production packaging.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol 57202-G52-05LF substitute for the Molex 0877591075 in production?

A: Yes. The 57202-G52-05LF meets all critical substitution parameters: 10 positions, 2 rows, 2.00mm pitch, surface mount, solder termination, and push-pull fastening. The difference in mating contact length (0.157" versus 0.150") does not affect substitution eligibility. Bulk packaging may require adjustment to procurement and assembly workflows.

Q: What is the difference between the two Amphenol tape and reel options?

A: The 57202-G53-05A09LF is configured with 9 positions loaded, while the 57202-G53-05ALF has all 10 positions loaded. Both include pick-and-place features and are supplied in tape and reel format. Selection depends on whether the application design requires all 10 positions or can operate with 9.

Q: Are there electrical performance differences between the Molex and Amphenol parts?

A: The Amphenol parts specify 2A (AC/DC) current rating and 200V (AC/DC) voltage rating. The Molex 0877591075 does not provide these electrical specifications in the available data. Both use gold-plated mating contacts with identical finish thickness (30.0µin / 0.76µm) and tin-plated posts.

Q: Does the contact material difference affect substitution?

A: The Molex part uses phosphor bronze contacts while the Amphenol parts use copper alloy contacts. Both materials are standard for this connector class and maintain compatibility with the specified gold plating and push-pull fastening system. Material selection does not preclude substitution.

Q: Can I use the 57202-G52-05LF in place of the tape and reel packaged original?

A: Yes, functionally the parts are equivalent. However, the 57202-G52-05LF is supplied in bulk packaging rather than tape and reel. This requires adjustment to pick-and-place assembly processes and may impact production efficiency depending on your manufacturing setup.

Q: Are all three substitute parts RoHS compliant?

A: Yes. All three Amphenol parts are RoHS Compliant. The original Molex part is ROHS3 Compliant. Both compliance levels are acceptable for equivalent substitution.
