TE Connectivity AMP Connectors 87527-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 87527-4 is a rectangular connector header designed for through-hole mounting applications. This vertical 4-position connector operates at a 0.100" (2.54mm) pitch and features male pin contacts with gold-plated mating surfaces. The connector is part of the AMPMODU Mod II series and maintains Active product status with full inventory availability. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component selection from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across critical electrical and mechanical parameters. The TE Connectivity 87527-4 and Hirose Electric A2-4PA-2.54DSA(71) share the following qualifying parameters:

Critical Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 4
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Contact Finish - Mating: Gold
• Contact Shape: Square
• Style: Board to Board or Cable
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Both parts are Active products with RoHS compliance and EAR99 ECCN classification. The Hirose substitute maintains functional and mechanical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 87527-4 and Hirose A2-4PA-2.54DSA(71) are Active products with current manufacturing status and full RoHS compliance. Selection between these parts is based on the following engineering criteria:

TE Connectivity 87527-4 is the primary specification. This part maintains AMPMODU Mod II series designation with 800 units in current inventory stock.

Hirose A2-4PA-2.54DSA(71) serves as a qualified substitute when primary sourcing is constrained. This part offers higher inventory availability at 2,556 units and includes specified operating temperature range (-55°C ~ 85°C), current rating (3A), and voltage rating (200V). The Hirose part features UL94 V-0 material flammability rating and ROHS3 compliance status.

Both parts share identical critical parameters: 4-position, 1-row, 0.100" pitch, through-hole solder termination, unshrouded male pin headers with gold-plated mating contacts and square contact geometry. Dimensional variations exist in contact lengths and insulation height; these differences do not affect functional compatibility in standard board-to-board or cable applications where the 2.54mm pitch standard is maintained.

Frequently Asked Questions (FAQ)

Q: What determines if the Hirose A2-4PA-2.54DSA(71) can substitute for the TE Connectivity 87527-4?

A: Substitution is valid when both parts share identical values across critical parameters: connector type (header), contact type (male pin), number of positions (4), number of rows (1), mating pitch (0.100"/2.54mm), mounting type (through hole), termination method (solder), fastening type (push-pull), shrouding (unshrouded), contact finish (gold), contact shape (square), and style (board to board or cable). Both parts meet these criteria.

Q: Are there dimensional differences between these parts?

A: Yes. The Hirose part has shorter contact lengths and a slightly taller insulation height compared to the TE Connectivity part. Specifically: TE Connectivity contact length mating is 0.318" (8.08mm) versus Hirose 0.236" (6.00mm); TE Connectivity insulation height is 0.090" (2.29mm) versus Hirose 0.100" (2.54mm). These dimensional variations do not affect compatibility in standard 2.54mm pitch applications.

Q: What is the difference in contact material between these parts?

A: The TE Connectivity 87527-4 uses Phosphor Bronze contacts, while the Hirose A2-4PA-2.54DSA(71) uses Brass contacts. Both materials are suitable for gold-plated mating surfaces and solder termination applications.

Q: What insulation materials are used in each part?

A: The TE Connectivity 87527-4 uses Polyamide (PA), Nylon, Glass Filled insulation. The Hirose A2-4PA-2.54DSA(71) uses Polybutylene Terephthalate (PBT) insulation. Both materials are black and suitable for through-hole mounting applications.

Q: Does the Hirose part provide electrical specifications that the TE Connectivity part does not?

A: Yes. The Hirose A2-4PA-2.54DSA(71) specifies operating temperature range (-55°C ~ 85°C), current rating (3A), and voltage rating (200V). The TE Connectivity 87527-4 does not provide these specifications in the available data. The Hirose part also includes UL94 V-0 material flammability rating.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 87527-4 is RoHS Compliant. The Hirose A2-4PA-2.54DSA(71) is ROHS3 Compliant. Both parts meet RoHS requirements.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in existing designs?

A: Functional interchangeability is supported by matching critical parameters across connector type, contact configuration, pitch, mounting method, and termination. Dimensional variations in contact length and insulation height require verification against specific PCB layout and mating connector specifications before implementation.
