MITI-3V1-6-10 Equivalent & Substitute Parts

Part Overview

The MITI-3V1-6-10 is a glass body reed switch manufactured by Littelfuse Inc., configured as a SPST-NO (Single Pole Single Throw - Normally Open) contact arrangement. This through-hole component is rated for 250mA DC switching at 170V DC with 10W power handling. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance, repair, and new design implementations where this switching characteristic is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MITI-3V1-6-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO to maintain identical switching behavior
• Mounting Type: Must be Through Hole to ensure PCB compatibility
• Termination Style: Must be Axial for lead compatibility
• Power Rating: Must be rated for 10W minimum
• Voltage - Switching DC: Must support 170V DC or higher
• Current - Switching: Must support 250mA DC or higher
• Operating Temperature Range: Must encompass -40°C to 125°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status

Three substitute parts meet these criteria with varying performance characteristics within the allowed parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

MITI-7-6-10 (Littelfuse Inc.) is the primary direct substitute. It maintains identical operate range (6 ~ 10AT), switching current (250mA DC), and voltage rating (170V DC) as the original MITI-3V1-6-10. Both components share the same manufacturer, glass body reed type, and ROHS3 compliance. The MITI-7-6-10 is currently active in production, ensuring long-term availability. Physical length differs by 0.221" (5.61mm), requiring verification of PCB layout constraints.

RI-70GP0710 (Comus International) provides enhanced current-switching capability (500mA AC/DC) while maintaining 170V DC voltage rating and 10W power handling. This substitute offers faster switching response (0.15ms operate time, 0.03ms release time) and extended operating temperature range (-55°C to 125°C). The component is active and ROHS3 compliant. Physical dimensions match the original part exactly. Current-carry rating is 400mA AC/DC, which is lower than the original 500mA DC specification.

KSK-1A80-1015 (Standex-Meder Electronics) is the manufacturer-recommended substitute. It delivers 500mA AC/DC switching current and maintains 170V DC voltage rating. The component features the highest operating temperature range (-40°C to 130°C) and is active in production with ROHS3 compliance. The operate range is higher (10 ~ 15AT) compared to the original 6 ~ 10AT specification. Physical length is 0.402" (10.2mm) shorter than the original part.

All three substitutes meet the mandatory substitution criteria. Selection depends on specific application requirements regarding operate range, switching speed, and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can MITI-7-6-10 be used as a direct replacement for MITI-3V1-6-10?

A: Yes. Both components share identical circuit configuration (SPST-NO), operate range (6 ~ 10AT), switching current (250mA DC), voltage rating (170V DC), power rating (10W), mounting type (Through Hole), and termination style (Axial). The primary difference is overall length: MITI-7-6-10 measures 1.590" versus 1.811" for the original. Verify PCB layout accommodates the shorter length.

Q: What are the key differences between RI-70GP0710 and the original MITI-3V1-6-10?

A: RI-70GP0710 doubles the switching current capacity to 500mA AC/DC and provides faster switching response (0.15ms operate time versus 0.45ms). It extends the operating temperature range to -55°C minimum. The voltage rating (170V DC) and power rating (10W) remain identical. Physical dimensions match exactly. The current-carry rating is 400mA AC/DC, which is lower than the original 500mA DC specification.

Q: Why is KSK-1A80-1015 listed as manufacturer-recommended?

A: KSK-1A80-1015 meets all mandatory substitution criteria and is designated as the manufacturer-recommended alternative in the original part documentation. It provides 500mA AC/DC switching current, maintains 170V DC voltage rating, and offers the widest operating temperature range (-40°C to 130°C). The operate range is higher (10 ~ 15AT), which does not prevent substitution but indicates different magnetic sensitivity characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MITI-7-6-10, RI-70GP0710, and KSK-1A80-1015 are all ROHS3 compliant, matching the original MITI-3V1-6-10 compliance status.

Q: Which substitute offers the fastest switching response?

A: RI-70GP0710 provides the fastest switching characteristics with 0.15ms operate time and 0.03ms release time, compared to 0.45ms and 0.2ms respectively for the original part.

Q: Do physical dimensions differ significantly between substitutes?

A: Yes. MITI-7-6-10 is 0.221" shorter (1.590" versus 1.811"). KSK-1A80-1015 is 0.402" shorter (1.409" versus 1.811"). RI-70GP0710 matches the original length exactly at 1.811". Verify PCB layout and mechanical clearances before selection.

Q: Can these substitutes be used interchangeably in all applications?

A: All three substitutes meet the core electrical and mechanical criteria for the MITI-3V1-6-10. However, differences in operate range, switching speed, and physical length may affect performance in specific applications. Operate range differences (6 ~ 10AT original versus 7 ~ 10AT or 10 ~ 15AT for substitutes) indicate varying magnetic sensitivity. Verify application requirements before final selection.
