Inventory availability varies across color variants: AT04-4P-YEL (1065 pcs), AT04-4P-BLU (1657 pcs), AT04-4P-BRN (1929 pcs), AT04-4P-GRN (1913 pcs), and AT04-4P-ORG (1619 pcs). Component selection may consider stock levels for supply chain optimization.
Frequently Asked Questions (FAQ)
Q: Can AT04-4P-BLU be used in place of AT04-4P-YEL without circuit redesign?
A: Yes. Both parts are parametrically equivalent rectangular connector receptacles with identical electrical and mechanical specifications. The only difference is housing color. No circuit redesign is required for substitution.
Q: Are the contacts included with the AT04-4P-YEL housing?
A: No. The AT04-4P-YEL is a receptacle housing only. Contacts are not included and must be sourced separately. This specification applies uniformly across all color variants in the AT04-4P family.
Q: What is the operating temperature range for all AT04-4P variants?
A: All AT04-4P color variants operate across the identical temperature range of -55°C to 125°C. Temperature performance is not affected by housing color selection.
Q: Do all AT04-4P variants meet the same compliance standards?
A: Yes. All variants—AT04-4P-YEL, AT04-4P-BLU, AT04-4P-BRN, AT04-4P-GRN, and AT04-4P-ORG—are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.
Q: What is the difference between the AT04-4P variants?
A: The AT04-4P family consists of 4-position rectangular connector receptacles that differ only in housing color. All electrical, mechanical, and environmental parameters remain constant across yellow, blue, brown, green, and orange variants.
Q: Is the AT04-4P-YEL sealed?
A: Yes. The AT04-4P-YEL features sealed housing design. This sealed specification applies to all color variants within the AT04-4P family.
Q: What mounting configuration does the AT04-4P-YEL support?
A: The AT04-4P-YEL is configured for free-hanging in-line mounting. This mounting type is identical across all AT04-4P color variants.
Q: How many rows of contacts does the AT04-4P-YEL accommodate?
A: The AT04-4P-YEL accommodates 2 rows of contacts in a 4-position configuration. This row arrangement is consistent across all substitute parts in the AT04-4P family.
