Substitute Part Grouping Explanation
Substitution eligibility for the 8-1241961-3 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (2), pitch (5.00mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), and fastening type (latch lock). All substitute parts maintain these core electrical and mechanical specifications.
Substitute parts are grouped into two categories based on material composition and thermal performance:
Category A: PA6/Nylon 6 Insulation Material — Parts 3-1241961-2, 6-1241961-2, and 7-1241961-2 utilize polyamide (PA6) nylon 6 insulation with operating temperature range of -40°C to 105°C. These parts are functionally equivalent to the main part with identical pitch, position count, and mounting characteristics.
Category B: PA/Nylon Insulation Material with Extended Temperature — Parts 5-928247-2 and 6-928247-2 feature polyamide (PA) nylon insulation with extended operating temperature range of -40°C to 110°C. Part 5-928247-2 is distinguished by green color housing, while 6-928247-2 maintains natural color. These parts support higher thermal environments.
Category C: PA66/Nylon 6/6 Insulation Material — Part 9-1241961-2 matches the main part's PA66 nylon 6/6 insulation composition with identical -40°C to 105°C operating temperature range.
All substitute parts maintain RoHS compliance, MSL 1 rating, and crimp contact termination with latch lock fastening.

A: All parts except 6-928247-2 carry MSL 1 (unlimited) rating. Part 6-928247-2 lists MSL as Not Applicable. This difference does not affect substitution eligibility for standard applications.
Q: What is the significance of the base product number difference between 1241961 and 928247?
A: The base product number indicates the original product family designation. Parts with base number 1241961 (8-1241961-3, 3-1241961-2, 6-1241961-2, 7-1241961-2, 9-1241961-2) share one product family, while parts with base number 928247 (5-928247-2, 6-928247-2) represent an alternative product family. Both families provide equivalent 2-position 5.00mm pitch receptacle housings with identical electrical and mechanical specifications.
Q: Can these connector housings be used interchangeably in existing assemblies?
A: Yes, all substitute parts maintain identical connector type (receptacle), contact type (female socket), position count (2), pitch (5.00mm), mounting type (free hanging in-line), contact termination (crimp), and fastening type (latch lock).
