Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MITI-3V1-6-8 is determined by the following critical parameters:

• Circuit configuration must remain SPST-NO
• Mounting type and termination style must be Through Hole with Axial leads
• DC switching voltage must meet or exceed 170V
• DC switching current must meet or exceed 250mA
• Rated power must meet or exceed 10W
• Operating temperature range must encompass -40°C to 125°C
• RoHS3 compliance is required

The three substitute parts listed below satisfy these criteria with varying degrees of parameter alignment and operational characteristics.

Parameter Comparison

Engineering Selection Recommendations

MITI-7-6-8 (Littelfuse Inc.) — Direct manufacturer alternative with identical operate range (6 ~ 8AT) and DC switching specifications (250mA at 170V). Maintains same temperature operating window and RoHS3 compliance. Product status is Active. This substitute provides the closest functional equivalence with minimal design impact.

RI-70GP0710 (Comus International) — Meets all critical substitution parameters with enhanced current capacity (500mA DC) and extended lower temperature rating (-55°C). Operates at identical 170V DC switching voltage with 10W rated power. Product status is Active with REACH Unaffected designation. Suitable for applications requiring higher current margin or expanded temperature range.

KSK-1A80-1015 (Standex-Meder Electronics) — Manufacturer-recommended alternative meeting all substitution criteria with 500mA DC switching capacity and 170V DC voltage rating. Extended upper temperature limit (130°C) and lowest capacitance specification (0.2 pF). Product status is Active with REACH Unaffected designation. Operate range is higher (10 ~ 15AT), indicating higher sensitivity threshold.

All three substitutes maintain ROHS3 compliance and Through Hole Axial termination required for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can MITI-7-6-8 be used as a direct drop-in replacement for MITI-3V1-6-8?

A: Yes. Both parts share identical SPST-NO circuit configuration, 6 ~ 8AT operate range, 250mA DC switching current, 170V DC switching voltage, and -40°C to 125°C operating temperature. Mounting type and termination style are identical (Through Hole, Axial). The MITI-7-6-8 is the closest functional equivalent.

Q: What is the primary difference between RI-70GP0710 and the original MITI-3V1-6-8?

A: The RI-70GP0710 has higher DC switching current capacity (500mA versus 250mA) and a lower minimum operating temperature (-55°C versus -40°C). The operate range is higher (7 ~ 10AT versus 6 ~ 8AT). All other critical parameters including 170V DC switching voltage, 10W rated power, and Through Hole Axial mounting remain compatible.

Q: Why does KSK-1A80-1015 have a higher operate range (10 ~ 15AT)?

A: Operate range defines the magnetic field strength required to activate the reed switch. A higher operate range (10 ~ 15AT) indicates the switch requires a stronger magnetic field compared to the original 6 ~ 8AT specification. This affects application compatibility based on magnet strength in the system design.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MITI-7-6-8, RI-70GP0710, and KSK-1A80-1015 are all ROHS3 Compliant, matching the original MITI-3V1-6-8 compliance status.

Q: What is the inventory status of these substitute parts?

A: MITI-7-6-8 has 893 Pcs in stock, RI-70GP0710 has 41,822 Pcs in stock, and KSK-1A80-1015 has 2,073 Pcs in stock. All are classified as New Original In Stock.
