Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-644803-0 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Pitch spacing (0.100" / 2.54mm), number of positions (10), contact type (male pin), voltage rating (250VAC), and operating temperature range (-55°C ~ 105°C) must remain identical.

Mechanical Parameters: Mounting type (through hole, right angle), shrouding configuration (shrouded - 4 wall), connector style (board to cable/wire), and contact geometry (square shape, 0.200" mating length, 0.130" post length) must be preserved.

Material & Compliance Parameters: Insulation material (polyester), contact material (copper alloy), flammability rating (UL94 V-0), and moisture sensitivity level (MSL 1) establish the baseline compatibility framework.

The substitute part 3-644803-0 maintains full equivalence across all specified parameters while offering active product status and improved compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The 3-644803-0 is the direct equivalent substitute for the obsolete 1-644803-0. Both parts maintain identical electrical and mechanical specifications within the MTA-100 series, ensuring functional interchangeability in all applications.

Product Status Consideration: The 1-644803-0 carries obsolete status, indicating discontinued manufacturing and limited long-term availability. The 3-644803-0 maintains active product status with confirmed inventory of 1399 pieces, providing assured procurement continuity.

Compliance Advantage: The 3-644803-0 achieves ROHS3 compliance, whereas the 1-644803-0 is RoHS non-compliant. This compliance upgrade aligns with current regulatory requirements for electronic components in regulated markets and applications.

Contact Finish Specification: The 1-644803-0 specifies tin-lead contact finish, while the 3-644803-0 uses tin finish. Both finishes are compatible with standard solder termination processes and provide equivalent electrical performance and reliability characteristics.

Packaging: The 3-644803-0 is supplied in bulk packaging, compared to the main part's unspecified packaging. This distinction affects procurement logistics but does not impact functional or electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 1-644803-0 and 3-644803-0 electrically interchangeable?

A: Yes. Both parts operate at 250VAC, support the same -55°C to 105°C temperature range, and maintain identical pitch spacing (0.100" / 2.54mm), position count (10), and contact configuration (male pin, square shape). Electrical performance is equivalent.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: Both tin-lead and tin finishes are compatible with standard solder termination processes. The tin finish in the 3-644803-0 represents a lead-free alternative that meets modern environmental and regulatory standards while maintaining equivalent electrical conductivity and reliability.

Q: Why is the 1-644803-0 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 3-644803-0 serves as the active replacement, ensuring continued availability and support for new designs and procurement requirements.

Q: Does the bulk packaging of the 3-644803-0 affect compatibility?

A: No. Packaging format does not impact electrical or mechanical compatibility. Bulk packaging is a procurement and logistics consideration only. The connector itself maintains identical form, fit, and function.

Q: Can I use the 3-644803-0 in existing designs specified for the 1-644803-0?

A: Yes. The 3-644803-0 is a direct substitute with identical mechanical mounting, electrical ratings, and connector geometry. No design modifications are required for component substitution.

Q: What is the advantage of ROHS3 compliance in the 3-644803-0?

A: ROHS3 compliance ensures the component meets current European Union and international regulatory requirements for restricted hazardous substances. This compliance status is required for many regulated applications and markets.

Q: Are the dimensional specifications identical between both parts?

A: Yes. Insulation height (0.343" / 8.71mm), contact mating length (0.200" / 5.08mm), contact post length (0.130" / 3.30mm), and all other dimensional parameters are identical, ensuring direct mechanical interchangeability.
