TE Connectivity 1969603-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1969603-8 is an 8-position rectangular connector receptacle housing from the VAL-U-LOK series. This component is a female socket receptacle designed for crimp termination with a 0.165" (4.20mm) pitch configuration and latch lock fastening. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, series discontinuation, or application-specific design requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1969603-8 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (8), pitch (0.165"/4.20mm), number of rows (2), row spacing (0.165"/4.20mm), mounting type (free hanging in-line), contact termination (crimp), and fastening type (latch lock). All identified substitute parts maintain these core electrical and mechanical specifications. Variations in color (natural versus black), insulation material composition (PA versus PA66 with or without glass fill), and operating temperature documentation do not prevent functional substitution when these core parameters are identical. Series designation differences (VAL-U-LOK, Mini-Fit Jr 5557, Mini-Fit Jr 45587) reflect manufacturer product line organization but do not affect connector interface compatibility.

Engineering Selection Recommendations

All six parts listed maintain identical core connector specifications and are classified as Active product status. The TE Connectivity 794954-8 provides direct series equivalence within the same manufacturer, with RoHS compliance and identical operating temperature range. The Molex 0039012080 offers natural color matching with the primary part and ROHS3 compliance with documented REACH unaffected status. The Molex 0039013085 and 0039039082 provide black housing alternatives with ROHS3 compliance and REACH unaffected status; however, operating temperature specifications are not documented for these variants. The Molex 0455870004 maintains full operating temperature specification (-40°C ~ 105°C) and ROHS3 compliance with REACH unaffected status, though MSL rating is not applicable. Selection should prioritize parts with complete compliance documentation and specified operating temperature ranges when application requirements demand full environmental performance data.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1969603-8 be directly replaced with the TE Connectivity 794954-8?

A: Yes. Both parts share identical electrical and mechanical specifications including 8 positions, 0.165" (4.20mm) pitch, 2-row configuration, crimp termination, and latch lock fastening. Both maintain -40°C ~ 105°C operating temperature range and MSL 1 rating. The primary difference is base product number designation within the VAL-U-LOK series.

Q: What are the differences between the natural and black housing variants?

A: The TE Connectivity 1969603-8 and Molex 0039012080 feature natural color housings. The Molex 0039013085 and 0039039082 feature black color housings. All other electrical and mechanical parameters remain equivalent. Color selection is determined by application aesthetics and PCB assembly requirements.

Q: Are Molex Mini-Fit Jr series connectors compatible with TE Connectivity VAL-U-LOK housings?

A: The substitute parts listed maintain identical connector interface specifications (8 positions, 0.165" pitch, 2 rows, crimp termination, latch lock fastening). Compatibility is determined by these core parameters, not series designation. Series names reflect manufacturer product line organization.

Q: What is the significance of the insulation material variations (PA versus PA66)?

A: Both polyamide (PA) and polyamide 66 (PA66) are nylon-based insulation materials suitable for the specified operating temperature range. PA66 variants may include glass fill for enhanced mechanical properties. These material variations do not prevent functional substitution when all core connector parameters are identical.

Q: Which substitute part should be selected if operating temperature specification is critical?

A: Parts with documented operating temperature ranges are TE Connectivity 1969603-8 (-40°C ~ 105°C), TE Connectivity 794954-8 (-40°C ~ 105°C), Molex 0039012080 (-40°C ~ 105°C), and Molex 0455870004 (-40°C ~ 105°C). The Molex 0039013085 and 0039039082 do not specify operating temperature limits.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts maintain RoHS compliance. The primary part and Molex variants are ROHS3 compliant. The TE Connectivity 794954-8 is RoHS compliant. All parts meet regulatory requirements for restricted substance elimination.

Q: What inventory availability should be considered for procurement?

A: Current inventory levels are provided for reference: 1969603-8 (1,219 pcs), 794954-8 (2,100 pcs), 0039012080 (213,760 pcs), 0039013085 (13,972 pcs), 0039039082 (25,886 pcs), and 0455870004 (51,126 pcs). Inventory status is subject to change and should be confirmed at time of procurement.

Q: Do all substitute parts include contacts?

A: No. All listed parts are connector housings only. Contacts are not included with any of these components and must be procured separately according to application requirements.
