TE Connectivity 787531-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 787531-1 is a 6-position header connector with male blades, designed for through-hole solder mounting on printed circuit boards. This connector operates within the Multi-Directional Interconnection System (MDI) series and features a 2.00mm pitch configuration with push-pull fastening. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to support ongoing procurement and design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 787531-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Header, Male Blades
• Number of positions: 6
• Pitch: 0.079" (2.00mm)
• Mounting type: Through Hole
• Number of rows: 1
• Termination method: Solder
• Contact material: Brass
• Contact finish: Gold
• Insulation material: Syndiotactic Polystyrene (SPS)
• Operating temperature range: -55°C to 105°C
• Series: Multi-Directional Interconnection System (MDI)

The substitute part 5787531-1 satisfies all mandatory matching parameters. However, the current rating differs between the main part (7 A) and the substitute (3 A), which represents a functional limitation that must be evaluated within the context of the specific application circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5787531-1 is the active equivalent substitute for the obsolete 787531-1. Both connectors share identical mechanical and electrical specifications across all critical parameters including connector geometry, pitch, mounting configuration, and operating temperature range.

Product Status Consideration: The 787531-1 is classified as obsolete, while the 5787531-1 maintains active product status with higher inventory availability (3283 units in stock versus 1051 units for the obsolete part). This status differential supports long-term supply chain continuity.

Compliance Consideration: The 5787531-1 is RoHS compliant, whereas the 787531-1 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 5787531-1 is the appropriate selection.

Current Rating Consideration: The primary electrical difference between these parts is the current rating specification. The 787531-1 is rated for 7 A, while the 5787531-1 is rated for 3 A. Circuit designs operating at current levels exceeding 3 A require evaluation of whether the reduced current rating of the substitute part is compatible with application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5787531-1 directly replace the 787531-1 in all applications?

A: The 5787531-1 is mechanically and geometrically identical to the 787531-1 and will physically fit all PCB designs and mating connectors. However, the current rating difference (3 A versus 7 A) must be evaluated against the specific circuit current requirements. If the application circuit operates at currents between 3 A and 7 A, the substitute part is not suitable.

Q: What is the significance of the RoHS compliance difference?

A: The 787531-1 is RoHS non-compliant, while the 5787531-1 is RoHS compliant. RoHS compliance is a regulatory requirement in many jurisdictions and for many original equipment manufacturers. New designs and applications subject to RoHS regulations must use the 5787531-1.

Q: Are there packaging differences between these parts?

A: The 787531-1 packaging specification is not provided in the available data. The 5787531-1 is supplied in tube packaging. Packaging differences do not affect electrical or mechanical compatibility but may impact handling, storage, and assembly processes.

Q: What is the base product number relationship?

A: The 787531-1 has a base product number of 787531, while the 5787531-1 has a base product number of 5787531. These base numbers indicate different product lines within the TE Connectivity MDI series, though the connectors themselves are functionally equivalent within the specified current rating constraints.

Q: Are both parts from the same manufacturer?

A: Yes, both the 787531-1 and 5787531-1 are manufactured by TE Connectivity AMP Connectors and belong to the Multi-Directional Interconnection System (MDI) series.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited moisture sensitivity. These connectors do not require special moisture control during storage or handling.
