Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 8-1971875-3 is determined by the following core parameters that must remain constant across all equivalent parts:

Fixed Parameters (Must Match):

• Connector type: Receptacle
• Number of positions: 9
• Pitch: 0.236" (6.00mm)
• Number of rows: 3
• Row spacing: 0.319" (8.10mm)
• Contact type: Tab
• Mounting type: Panel Mount, Snap-In
• Fastening type: Latch Lock
• Contact termination: Crimp
• Moisture sensitivity level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Insulation material composition (Polyamide PA vs. Polybutylene Terephthalate PBT vs. Polyamide PA6 Glass Filled)
• Color (Natural vs. Gray)
• Operating temperature range (up to 150°C vs. up to 105°C)
• Series designation (Power Triple Lock, High Temp vs. Power Triple Lock)
• RoHS certification version (RoHS vs. ROHS3)
• REACH status classification

The three identified substitute parts maintain all fixed parameters while permitting variation in material composition, color, and thermal rating based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 8-1971875-3

The 8-1971875-3 is the baseline reference part with the highest operating temperature rating (-55°C ~ 150°C) and polyamide nylon insulation material. This part is RoHS Compliant and suitable for high-temperature applications requiring the extended thermal range. Selection of this part is appropriate when the full 150°C upper temperature limit is a design requirement.

Substitute 1-1971875-3

The 1-1971875-3 maintains natural color and the Power Triple Lock, High Temp series designation but reduces the operating temperature range to -55°C ~ 105°C and substitutes polybutylene terephthalate (PBT) insulation material. This part achieves ROHS3 Compliant status. Selection is appropriate when ROHS3 certification is required and the application does not exceed 105°C operating temperature.

Substitute 5-1971875-3

The 5-1971875-3 changes color to gray and uses polybutylene terephthalate (PBT) insulation material with an operating temperature range of -55°C ~ 105°C. This part maintains RoHS Compliant status and the Power Triple Lock, High Temp series designation. Selection is appropriate when gray color is required for visual identification or application-specific requirements and the application does not exceed 105°C operating temperature.

Substitute 5-2232356-3

The 5-2232356-3 uses polyamide PA6 nylon 6 glass-filled insulation material with gray color and an operating temperature range of -55°C ~ 105°C. This part is designated as Power Triple Lock series (without High Temp designation) and maintains RoHS Compliant status. Selection is appropriate when glass-filled polyamide material properties are required, gray color is specified, and the application does not exceed 105°C operating temperature.

All substitute parts maintain active product status and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard handling and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can the 1-1971875-3 be used as a direct replacement for the 8-1971875-3?

A: The 1-1971875-3 is mechanically and electrically compatible with the 8-1971875-3 for applications operating at or below 105°C. The primary differences are the reduced maximum operating temperature (105°C vs. 150°C), the change in insulation material from polyamide to polybutylene terephthalate, and the upgrade to ROHS3 certification. If your application requires operation above 105°C, the 8-1971875-3 must be used.

Q: What is the difference between the natural and gray color variants?

A: The 8-1971875-3 and 1-1971875-3 are supplied in natural color, while the 5-1971875-3 and 5-2232356-3 are supplied in gray color. Color selection is typically driven by application requirements for visual identification, connector organization, or customer specifications. All color variants maintain identical electrical and mechanical performance within their respective temperature ratings.

Q: Why does the 5-2232356-3 have a different base product number?

A: The 5-2232356-3 uses a different base product number (2232356 vs. 1971875) because it incorporates glass-filled polyamide PA6 insulation material rather than standard polyamide or polybutylene terephthalate. This material composition change results in a distinct product designation while maintaining the same connector form factor, pitch, and mounting characteristics.

Q: Are all substitute parts RoHS compliant?

A: All four parts (8-1971875-3, 1-1971875-3, 5-1971875-3, and 5-2232356-3) are RoHS compliant. The 1-1971875-3 specifically achieves ROHS3 certification, which represents a more recent version of the RoHS standard. Selection between RoHS and ROHS3 compliant variants depends on your regulatory or customer requirements.

Q: What is the significance of the operating temperature range difference?

A: The 8-1971875-3 supports continuous operation from -55°C to 150°C, while the substitute parts (1-1971875-3, 5-1971875-3, and 5-2232356-3) support operation from -55°C to 105°C. The reduced upper temperature limit in substitute parts is a direct result of the insulation material composition. Applications requiring sustained operation above 105°C must use the 8-1971875-3.

Q: Can I mix different substitute parts in the same assembly?

A: All substitute parts maintain identical electrical and mechanical specifications for connector pitch, position count, row spacing, mounting type, and fastening mechanism. Mixing different variants in the same assembly is permissible from a functional standpoint, though design documentation should specify which part number is used in each location to ensure proper procurement and traceability.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates that the component has unlimited shelf life and does not require special moisture-controlled storage conditions. All four parts in this comparison carry MSL 1 rating, meaning they can be stored and handled using standard industrial practices without desiccant packaging or controlled humidity environments.

Q: Are contacts included with these connector housings?

A: No. All four parts (8-1971875-3, 1-1971875-3, 5-1971875-3, and 5-2232356-3) are connector housings only. Contacts must be procured separately and crimped into the housing according to TE Connectivity specifications.
