Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 644488-7 is determined by strict alignment with the following critical parameters: connector type (header), contact type (male pin), number of positions (7), number of rows (1), pitch spacing (0.100"/2.54mm), mounting configuration (through hole, right angle), shrouding style (shrouded - 4 wall), termination method (solder), voltage rating (250VAC), and operating temperature range (-55°C ~ 105°C).

The substitute parts identified maintain these core electrical and mechanical specifications, ensuring functional compatibility in applications originally designed for the 644488-7. Variations in secondary parameters such as contact finish, contact material composition, insulation material additives, and fastening mechanism do not preclude substitution when primary parameters remain constant.

Engineering Selection Recommendations

2-644488-7 (Direct Substitute - Recommended Primary Choice)

The 2-644488-7 represents the direct equivalent to the obsolete 644488-7. Both components share identical electrical and mechanical specifications, including connector type, contact configuration, pitch spacing, mounting orientation, and voltage/temperature ratings. The primary distinction is product status: the 2-644488-7 is active and currently in production. Additionally, the 2-644488-7 achieves ROHS3 compliance, whereas the original 644488-7 is non-compliant. This substitute is suitable for direct replacement in all applications originally specified for the 644488-7.

0901362207 (Similar Substitute - Alternative Option)

The Molex 0901362207 provides functional substitution based on matching core parameters: 7-position header configuration, 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, solder termination, and UL94 V-0 flammability rating. This component is active and ROHS3 compliant. Differences include contact material (brass versus copper alloy), contact finish (gold mating surface versus tin), insulation material composition (glass-filled polyester), and fastening mechanism (latch holder versus friction lock). The 0901362207 is applicable in applications where these secondary parameter variations are acceptable and where Molex component qualification is permitted.

Frequently Asked Questions (FAQ)

Q: Can the 2-644488-7 be used as a direct replacement for the 644488-7?

A: Yes. The 2-644488-7 maintains all critical electrical and mechanical parameters of the 644488-7, including connector type, position count, pitch spacing, mounting configuration, voltage rating, and operating temperature range. The components are functionally equivalent for board-to-cable/wire interconnection applications.

Q: What is the primary advantage of selecting the 2-644488-7 over the original 644488-7?

A: The 2-644488-7 is an active product with current manufacturing support, whereas the 644488-7 is obsolete. Additionally, the 2-644488-7 achieves ROHS3 compliance, meeting current regulatory requirements for electronic component procurement.

Q: Under what conditions would the Molex 0901362207 be selected instead of the 2-644488-7?

A: The 0901362207 is selected when design specifications explicitly permit or require Molex components, when gold-plated mating contacts are required for enhanced corrosion resistance, or when the latch holder fastening mechanism is preferred over friction lock. The glass-filled polyester insulation material may also be advantageous in applications requiring enhanced mechanical strength.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 644488-7 is supplied in unspecified packaging, the 2-644488-7 is supplied in bulk packaging, and the 0901362207 is supplied in tray packaging. Packaging selection should align with procurement and assembly process requirements.

Q: What is the significance of the contact finish differences between these parts?

A: The 644488-7 and 2-644488-7 feature tin-lead contact finish, while the 0901362207 features gold mating surface with tin post finish. Gold plating provides superior corrosion resistance and contact reliability in high-reliability applications, though it increases component cost. Tin finish is suitable for general-purpose applications with standard environmental conditions.

Q: Do all three parts meet the same flammability and regulatory standards?

A: All three parts meet UL94 V-0 material flammability rating and are classified under ECCN EAR99 and HTSUS 8536.69.4040. The 2-644488-7 and 0901362207 are ROHS3 compliant, while the original 644488-7 is non-compliant. All three parts have moisture sensitivity level 1 (unlimited).

Q: What is the inventory status of these parts?

A: The 644488-7 has 960 pieces in stock (obsolete status), the 2-644488-7 has 1136 pieces in stock (active), and the 0901362207 has 848 pieces in stock (active). Procurement should prioritize active parts to ensure long-term supply chain continuity.
