TE Connectivity 1586587-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1586587-4 is a rectangular connector header, vertical mount, 4-position configuration with 4.20mm pitch spacing. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and maintenance applications. The connector features through-hole solder termination, shrouded 4-wall design, and latch holder fastening suitable for general purpose, industrial, and lighting applications. Substitute parts must maintain electrical and mechanical compatibility across connector pitch, position count, row configuration, mounting type, and termination method.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1586587-4 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

Pitch - Mating: 0.165" (4.20mm)
Number of Positions: 4
Number of Rows: 2
Row Spacing - Mating: 0.165" (4.20mm)
Connector Type: Header
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder
Shrouding: Shrouded - 4 Wall
Contact Shape: Square
Insulation Height: 0.555" (14.10mm)
Contact Length - Post: 0.138" (3.50mm)
Insulation Material: Polyamide (PA), Nylon

All identified substitute parts meet these mandatory parameters. Variations in contact finish material, fastening type (latch holder versus locking ramp), and flammability rating do not preclude substitution when the core electrical and mechanical interfaces remain identical. Substitute parts from Molex (Mini-Fit BMI 42440, Mini-Fit HCS 44474, and Mini-Fit Plus HCS 46011 series) provide functional equivalence for board-to-board or cable applications.

Engineering Selection Recommendations

All identified substitute parts maintain functional compatibility with the TE Connectivity 1586587-4 across critical electrical and mechanical interfaces. Selection among substitute options is determined by application-specific requirements and compliance considerations:

For applications requiring UL94 V-0 flammability rating: Parts 0015286042, 0460110402, and 0460110403 meet this specification. Part 0460110402 provides tin contact finish with copper alloy material, while 0460110403 offers gold contact finish for enhanced corrosion resistance.

For applications with standard flammability requirements: Parts 0015246041, 0444740411, and 0460110400 are suitable, offering UL94 V-2 rating. Part 0015246041 provides brass contact material with tin finish in bulk packaging. Part 0444740411 offers copper alloy material with board guide feature. Part 0460110400 features locking ramp fastening with copper alloy construction.

For high-volume procurement: Part 0015286042 provides the largest available inventory (16035 units) in tray packaging, supporting production continuity.

For contact finish considerations: Gold-plated options (0015286042 and 0460110403) provide superior corrosion resistance compared to tin-plated alternatives, suitable for extended storage or harsh environmental conditions.

All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the Molex Mini-Fit BMI 42440 series parts directly replace the TE Connectivity 1586587-4?

A: Yes. Parts 0015246041 and 0015286042 maintain identical pitch (4.20mm), position count (4), row configuration (2), mounting type (through hole), and solder termination. Both feature shrouded 4-wall design with square contacts and matching insulation height. Functional compatibility is established across all critical connector interfaces.

Q: What is the difference between latch holder and locking ramp fastening types?

A: Both fastening mechanisms provide secure mating retention. Latch holder fastening (used in 1586587-4, 0015246041, 0015286042, 0444740411) employs latching tabs for engagement. Locking ramp fastening (used in 0460110400, 0460110402, 0460110403) utilizes ramp-based locking geometry. Both are functionally equivalent for board-to-board or cable applications with identical mating force characteristics.

Q: Are there electrical performance differences between tin and gold contact finishes?

A: Contact finish does not alter electrical performance in standard applications. Tin finish (1586587-4, 0015246041, 0444740411, 0460110400, 0460110402) provides cost-effective corrosion resistance. Gold finish (0015286042, 0460110403) offers enhanced corrosion resistance and is preferred for applications with extended storage periods, high-humidity environments, or critical reliability requirements.

Q: Does the UL94 V-0 versus V-2 flammability rating affect connector functionality?

A: Flammability rating reflects insulation material performance under fire exposure and does not affect electrical or mechanical connector function. Selection between UL94 V-0 and V-2 is determined by application safety standards and regulatory requirements, not connector compatibility.

Q: What packaging options are available for substitute parts?

A: Molex substitute parts are supplied in bulk packaging (0015246041), tray packaging (0015286042, 0460110400, 0460110402, 0460110403), or unspecified packaging (0444740411). Packaging selection does not affect connector performance and is determined by procurement volume and handling requirements.

Q: Are all substitute parts currently in active production status?

A: Yes. All identified Molex substitute parts (0015246041, 0015286042, 0444740411, 0460110400, 0460110402, 0460110403) are classified as active products, ensuring long-term availability and supply continuity compared to the obsolete TE Connectivity 1586587-4.

Q: Can substitute parts be intermixed in the same application?

A: Yes. All substitute parts maintain identical pitch, position count, row spacing, mounting type, and termination method. Intermixing is functionally compatible. However, fastening type variation (latch holder versus locking ramp) and contact finish differences should be documented in assembly procedures for consistency.
